Description
Technical Field
[0001] This utility model relates to the field of hot pressing device technology, and in particular to a seamless hot pressing device for splicing ultra-thin fabrics. Background Technology
[0002] In the textile processing industry, seamless splicing technology for lightweight fabrics is crucial. Traditional sewing processes leave needle holes on the fabric surface, which not only compromises the fabric's waterproofness, breathability, and overall aesthetics, but may also cause fabric damage due to friction from the needle holes. This is especially unsuitable for applications such as skiwear, swimwear, and seamless underwear, where flatness and sealing are extremely important. Seamless splicing hot press machines for lightweight fabric garments achieve needle-hole-free bonding by precisely controlling temperature, pressure, and time, utilizing hot melt adhesive film or the fabric's own hot-melt properties, thus avoiding the drawbacks of traditional sewing.
[0003] Existing fabric hot pressing splicing equipment typically uses a fixed heating plate combined with a mechanical clamping mechanism to position the fabric. The splicing area is heated by an electric heating element, and pressure is provided by a cylinder or lead screw drive. In the cooling process, it mostly relies on natural environmental heat dissipation or a simple fan cooling device to remove heat through air convection.
[0004] However, existing equipment has some shortcomings in the cooling process. Since the adhesive layer at the fabric splicing point is still in a semi-molten state after hot pressing, if only natural cooling or non-uniform air cooling is used, the uneven curing speed of the adhesive layer will cause the splicing area to shrink and deform, which will affect the flatness and structural stability of the splicing point. Especially in ultra-thin fabrics, due to their low strength, they are more prone to irreversible deformation due to uneven cooling, which will affect the finished product qualification rate. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a seamless hot-pressing device for splicing ultra-thin fabrics. It aims to improve the problem that after hot pressing, the adhesive layer at the fabric splicing point is still in a semi-molten state. Relying solely on natural cooling or non-uniform air cooling, the uneven curing speed of the adhesive layer will cause the splicing area to shrink and deform, affecting the flatness and structural stability of the splicing point.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a seamless splicing hot pressing device for ultra-thin fabrics, comprising a base, a bracket fixedly connected to the upper surface of the base, a rotating column rotatably connected to the upper surface of the base, one end of the rotating column rotatably connected to the inner wall of the bracket, a rotating plate fixedly connected to the outer wall of the rotating column, a hydraulic rod II fixedly connected to the upper surface of the rotating plate, a fixed plate fixedly connected to the output end of the hydraulic rod II, a heating plate fixedly connected to the lower surface of the fixed plate, and a cooling assembly provided on the upper surface of the rotating plate;
[0007] The cooling assembly includes a cooling box, which is fixedly connected to the upper surface of a rotating plate.

[0008] Furthermore, a hydraulic rod is fixedly connected to the upper surface of the base, a rack is fixedly connected to the output end of the hydraulic rod, and a gear is fixedly connected to the outer wall of the rotating column, with the gear teeth meshing with the rack teeth.
[0009] Furthermore, a sliding groove is fixedly connected to the upper surface of the base, and the inner wall of the sliding groove is slidably connected to one side of the outer wall of the rack.
[0010] Furthermore, a hydraulic rod three is fixedly connected to the upper surface of the rotating plate, and the output end of the hydraulic rod three is fixedly connected to the upper surface of the bellows.
[0011] Furthermore, a second sliding groove is fixedly connected to the upper surface of the base, a slide frame is slidably connected to the inner wall of the second sliding groove, and a support plate is fixedly connected to the upper surface of the slide frame.
[0012] Furthermore, a slide rail is fixedly connected to the upper surface of the base, a hydraulic rod four is fixedly connected to one side of the outer wall of the slide rail, a slider is fixedly connected to the output end of the hydraulic rod four, and the lower surface of the slider is slidably connected to the upper surface of the slide rail.
[0013] Furthermore, a rotating shaft is fixedly connected to one side of the outer wall of the slider, a pressure plate is rotatably connected to one end of the rotating shaft, and a silicone block is fixedly connected to one side of the outer wall of the pressure plate.

[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, the hydraulic rod pushes the air box and the lower copper plate downwards to get close to the fabric splicing area after hot pressing. The fan in the cooling box operates synchronously, delivering cold air to the air box through the air duct. The air box disperses the cold air to the copper plate, and the copper plate evenly conducts the cold energy to the fabric splicing area for rapid cooling and shaping.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figure 1 and Figure 2This utility model provides an embodiment of a seamless hot-pressing device for ultra-thin fabrics, comprising a base 1, which supports the entire device and provides a stable working platform to ensure no shaking during hot pressing and cooling. A second slide groove 18 is fixedly connected to the upper surface of the base 1, and a slide frame 19 is slidably connected to the inner wall of the second slide groove 18. A support plate 20 is fixedly connected to the upper surface of the slide frame 19. The second slide groove 18, in conjunction with the slide frame 19, moves the support plate 20, achieving the effect of precisely moving the support plate 20 containing the fabric directly below the hot pressing or cold pressing station. A bracket 2 is fixedly connected to the upper surface of the base 1, supporting a rotating column 3 and a rotating plate 8 to ensure structural stability during the switching between hot pressing and cooling stations. A rotating column 3 is rotatably connected to the upper surface of the base 1, with one end of the rotating column 3 rotatably connected to the inner wall of the bracket 2. A rotating plate 8 is fixedly connected to the outer wall of the rotating column 3. A second hydraulic rod 9 is fixedly connected to the upper surface of the rotating plate 8, and a fixed... A fixed plate 10 has a heating plate 11 fixedly connected to its lower surface. A hydraulic rod 9 is used to push the fixed plate 10 and the heating plate 11 downwards onto the fabric, so that the heating plate 11 contacts and heats the fabric, achieving hot melt adhesive bonding and completing seamless splicing. A cooling component is provided on the upper surface of the rotating plate 8. A hydraulic rod 4 is fixedly connected to the upper surface of the base 1, and a rack 5 is fixedly connected to the output end of the hydraulic rod 4. A slide groove 7 is fixedly connected to the upper surface of the base 1. The slide groove 7 is used to limit the movement trajectory of the rack 5, ensuring that the rack 5 slides smoothly along a straight line and preventing the rack 5 from deviating during movement. The inner wall of the slide groove 7 is slidably connected to one side of the outer wall of the rack 5. A gear 6 is fixedly connected to the outer wall of the rotating column 3. The tooth end of the gear 6 meshes with the tooth end of the rack 5. The hydraulic rod 4 is used to push the rack 5 to slide straight along the slide groove 7, thereby driving the rotating column 3 to rotate through the meshing transmission of the rack 5 and the gear 6, realizing the effect of rapid switching between the hot pressing station and the cooling station.
[0027] Reference Figure 3A slide rail 21 is fixedly connected to the upper surface of the base 1. A hydraulic rod 22 is fixedly connected to one side of the outer wall of the slide rail 21. A slider 23 is fixedly connected to the output end of the hydraulic rod 22. The hydraulic rod 22 pushes and pulls the slider 23 to move along the slide rail 21, providing a power basis for the rotation of the pressure plate 25. The lower surface of the slider 23 is slidably connected to the upper surface of the slide rail 21. A rotating shaft 24 is fixedly connected to one side of the outer wall of the slider 23. One end of the rotating shaft 24 is rotatably connected to the pressure plate 25. A vertical rod 27 is fixedly connected to the upper surface of the base 1. A rotating shaft 28 is fixedly connected to one side of the outer wall of the vertical rod 27. One end of the rotating shaft 28 is rotatably connected to the pressure plate 25. The rotating connection is attached to the inner wall of the pressure plate 25. The rotating shaft 24 and the rotating shaft 28 work together to rotate the pressure plate 25. When the slider 23 moves, it drives the pressure plate 25 to rotate through the rotating shaft 24. The rotating shaft 28 serves as the rotation fulcrum at the other end of the pressure plate 25, realizing the pressing action of the pressure plate 25 against the edge of the fabric. This ensures that the fabric does not shift during the hot pressing and cooling process, and improves the splicing accuracy. A silicone block 26 is fixedly connected to one side of the outer wall of the pressure plate 25. The silicone block 26 is made of flexible material to prevent the pressure plate 25 from directly contacting the ultra-thin fabric and causing damage, thus ensuring the stability of the fabric position during the hot pressing and cooling process.
[0028] Reference Figure 4 and Figure 5 The cooling assembly includes a cooling box 13, which consists of a sealed box and a semiconductor cooling chip. The semiconductor cooling chip generates cold air and controls the cooling temperature, providing a stable cold source for the seams of ultra-thin fabrics. This is a well-known active cooling technology, which will not be elaborated further here. The cooling box 13 is fixedly connected to the upper surface of the rotating plate 8. A fan 14 is fixedly connected to the inner wall of the cooling box 13. An air duct 15 is fixedly connected to the output end of the fan 14. An air box 16 is fixedly connected to one end of the air duct 15. The fan 14, in conjunction with the air duct 15, delivers cold air, achieving the effect of quickly transferring the cold air inside the cooling box 13 to the air box 16. The upper surface of the rotating plate 8 is fixedly connected to... A hydraulic rod 12 is provided, with its output end fixedly connected to the upper surface of the air box 16. The hydraulic rod 12 is used to push the air box 16 and the copper plate 17 downward, so that the cooling components are close to the fabric splicing area after hot pressing, ensuring that the cold energy is efficiently transferred to the target area. The lower surface of the air box 16 is fixedly connected to the copper plate 17, which works with the air box 16 to transfer the cold energy. The air box 16 guides the cold air into the copper plate 17, and the high thermal conductivity of the copper plate 17 is used to achieve the effect of uniformly distributing the cold energy to the fabric splicing area over a large area, thereby achieving rapid cooling and shaping of the fabric and avoiding shrinkage and deformation caused by floating changes when the splicing adhesive is not fully cured, thus ensuring the splicing quality.
[0029] Working principle: When seamless splicing of ultra-lightweight fabrics is required, the operator first lays the ultra-lightweight fabric to be spliced flat on the pallet 20. By pushing the slide 19 to slide along the slide rail 18, the pallet 20 is moved directly below the hot pressing station. Then, the hydraulic rod 22 is activated, pulling the slider 23 to move in the opposite direction to the pallet 20 along the slide rail 21. When the slider 23 moves, the rotation characteristics of the rotating shaft 24 and the rotating shaft 28 drive the pressure plate 25 to make the silicone block 26 on the pressure plate 25 close to the surface. The flexible material of the silicone block 26 at the edge of the material is adapted to the easily damaged characteristics of ultra-thin fabrics. The fabric is clamped by the rotation of the pressure plate 25, which fixes the position of the fabric from all sides, ensuring the stability of the fabric position during hot pressing and cooling, and improving the splicing accuracy. Then, the hydraulic rod 29 is activated to push the fixing plate 10 and the lower electric heating plate 11 to press down on the fabric. The electric heating plate 11 is preheated to a temperature suitable for splicing ultra-thin fabrics. When it comes into contact with the fabric, the heat is used to heat-melt and bond the fabric splicing area, completing the seamless splicing.
[0030] Secondly, after hot pressing, the rack 5 is pushed by the hydraulic rod 4 to slide linearly along the slide groove 7. The rack 5 meshes with the gear 6 on the rotating column 3, driving the rotating column 3 to rotate, thereby rotating the rotating plate 8 and switching between hot pressing and cooling positions. Then, the hydraulic rod 12 is activated, pushing the air box 16 and the lower copper plate 17 down to the fabric splicing area after hot pressing. The fan 14 in the cooling box 13 operates synchronously, delivering cold air to the air box 16 through the air duct 15. The air box 16 disperses the cold air to the copper plate 17. The copper plate 17, with its good thermal conductivity, evenly conducts the cold air to the fabric splicing area, quickly cooling and shaping it, making the splicing structure stable. This avoids shrinkage and deformation caused by uneven curing speed of the fabric adhesive layer and fluctuation of the splicing adhesive, thus ensuring the splicing quality.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
